"Human choices affect nature and nature affects human choice". This research is investigated irrigation development on lagoon fisheries in Sri Lanka. Spatial variation of the lagoon system is derived from the land use maps. Information on biological changes of the lagoon and bio-economic conditions were obtained from the secondary data....
Coastal and marine spatial planning (CMSP) is a process for improving the management of ocean resources in order to promote their sustainable development. One of the most challenging spatial planning issues in New England now concerns the siting of offshore renewable energy facilities, mainly wind farms. Commercial fishermen are among...
Ghana's coast is identified with artisanal fishers who use wooden carved canoes and traditional fishing gears. However, little study has been conducted to assess the performance of this industry in terms of its efficiency. This study aims to analyse the technical efficiency and its determinants of the artisanal fishers in...
This paper is a compilation of several themes that addresses how Te Arawa iwi Trusts are utilising kaitiakitanga; traditional methods, practices and customs to manage freshwater environments and freshwater fisheries. Te Arawa is a central north island indigenous tribe of Aotearoa/New Zealand. Several deeds of settlement have been signed with...
In 1986, New Zealand implemented the world’s first comprehensive individual transferable quota management system for fisheries, designed to ensure sustainable use of fish resources by restricting take levels. Today, fewer people are fishing less frequently, often using with more efficient capture technologies. Drawing on ethnographic research with Maori fishing communities...
Payments for ecosystem services (PES) are positive incentives offered to producers or resource owners in exchange for the provision of a given ecosystem service, such as biodiversity, water regulation, food, recreation and tourism. Interest in applying this economic instrument within the aquatic ecosystems has increased alongside a growing interest in...
Bycatch reduction policies, traditionally focused on command-and-control at-sea measures, can be reframed to a broader-based biodiversity conservation and ecosystem management strategy. More cost- and ecologically-effective bycatch mitigation measures may directly and more effectively increase impacted populations elsewhere in their geographic range or life cycle. At-sea bycatch reduction faces diminishing returns...
We investigate the effects of incorporating a fixed input on equilibrium profits and biomass. We first set up a theoretical model with an input that is fixed in the short-run (vessel size) but that can be used with a variable input at suboptimal capacity. We use this model to get predictions for...
Anchovy fisheries in Indonesia faces a declining state in the next decade. This research investigates some factors contributing to a reduction of anchovy resources. It was carried out in Krueng Raya Bay-Aceh from September to October 2012. Survey and interviews were implemented to explore the state of anchovy. Primary and...
Optimal and sustainable fisheries industry can only be achieved with proper planning through
the implementation of appropriate management instruments as well. Fisheries resources
accounting is one of the planning instruments, which should be used as a main reference of
Fisheries Management Plan. In general, fisheries accounting provide insights for policy...
